Couple of thoughts after skimming the article. Consider weighing the importance of being able to upgrade or change uC. Don't choose a controller made by only one manufacturer (unless there is a level of certainty or confidence in their continued production/support and profitability). It would be unfortunate for example, if you used an atmega microcontroller and they went out of business, or changed their strategy and abandoned a platform, requiring you to switch to an alternative and rewrite some or all of your code. Having a codebase that can be made to run on different platforms easily would be ideal.

If there is a good chance, after a small order, you realize from feedback you are missing some crucial features and need to make changes, changes which require more it's higher or more precise clock, or whatever, make sure that the jump to the next size chip doesn't abandon or make a drastic jump in price or available volume. If you plan to manufacturer your product for a long time, ensure that you are confident in the availability of quantities at similar price for however long you expect to require it. Always be wary of jumping on board anything brand new. The Intel Edison/Curie for example based on the Quark ended up having an unfixable segfault, and was virtually abandoned shortly after it's release.
